While the show has avoided it for practical reasons, The Walking Dead creator Robert Kirkman would still like to see Rick lose his hand on the TV series.
That said, The Walking Dead has proven willing to ignore major events from the comic, so perhaps Rick will suffer an even worse injury.
The Walking Dead played a variation on a character losing their hand in the first season, however, where Merle Dixon is forced to chop his off to escape from cuffs – an injury he blamed on Rick.
In The Walking Dead comic this occurred in Issue #28, in which Rick is being interrogated by The Governor, who cuts off his hand when he refuses to answer questions.
